Research on Phase-Locked Loop Control and Its Application
In view of the importance of the phase locked loop (PLL) in the control of inverter,the SOGI-QSG based single phase PLL is taken as the research object,and its operating principle and control performance are analyzed in detail,which provides reference for the design of the phase locked loop.Aiming at the PLL based islanding detection methods have adverse effects on the power supply quality of the distributed generation (DG),this paper proposes a PLL based passive islanding detection method,which adds time delay in PLL control and can effectively improve the power quality of the DG supply,the simulation results verify the effectiveness of the proposed islanding detection method.
